FAQs
1.What is a PPTC fuse?
A PPTC fuse is a resettable overcurrent protection device that increases its resistance when excessive current flows and automatically resets after the fault is removed.
2.How does it compare to traditional fuses?
Traditional fuses are single-use and must be replaced after tripping, while PPTC fuses reset automatically and require no maintenance—ideal for consumer and portable electronics.
3.How does a PPTC fuse work?
During overcurrent, the polymer material heats up and expands, sharply increasing resistance to limit current. After cooling, it returns to its low-resistance state, restoring normal operation.
4.What is the difference between PPTC and PTC?
PPTC is a polymer-based PTC device designed specifically for resettable overcurrent protection, while standard PTC components are typically used for temperature sensing or inrush current limiting.
5.What is the difference between NTC and PTC?
NTC resistance decreases as temperature rises (used for sensing and inrush limiting), while PTC resistance increases with temperature (used for protection or heating functions).
